dc.description.abstract	A recently proposed modification of the viscoelastic Leonov model is employed as a stress calculator in FEM analysis with a full u-v-p-numerical scheme of the coextrusion flow in multi-manifold flat dies with 30 and 90 degree entrance angles. It is shown that the predicted stresses, interface location and streamlines fields are in a good agreement with the measurements. It is also revealed that the extensional viscosity has to be used in the modeling of the coextrusion flow to confirm experimental data.	en
